Stad, Stamford, Conn., assignors to Baldwin-Gegenheimer Corporation, Stamford, Conn, a corporation of New York Filed Nov. 28, 1966, Ser. No. 597,258 Int. Cl. B4113 31/00; F1611 25/12, 25/16 U.S. Cl. 101349 4 Claims ABSTRACT OF THE DISCLOSURE This invention relates to inking rolls for printing presses and more specifically relates to a new and improved vibrating inking roll of the type employed in printing presses for effecting an even distribution of ink upon large inking surfaces.

It is well known in the printing machinery art that the ink is applied intermittently to a large inking cylinder by means of a doctor or applicator. In order to transform this intermittent ink supply into an evenly distributed film suitable for application to the form or plate, relatively small ink distributing rolls are positioned around and in contact with an inking cylinder as well as with a number of vibrating rollers to cause the ink to be uniformly distributed to a plurality of inking rollers in contact with the form or plate. These inking rolls or form rollers are in contact with the vibrating rolls which are reciprocated in an axial direction so that the ink is evenly distributed.

A vibrating roller of this general type is described in United States Patent No. 2,826,989, granted March 18, 1958 to H. W. Gegenheimer, et al.

The present invention relates to a new and improved vibrating roller which has relatively few parts, is adaptable for use in different size presses and which is constructed to provide a continuous and smoothly operating reciprocating roller for even ink distribution. The invention is characterized by its relatively simple mechanical construction which provides for a smooth, trouble free conversion of the rotational movement of the roller to a rotary and vibratory motion. The construction of the vibrating roller in accordance with this invention provides a quietly working yet rugged construction which can withstand many hours and years of steady troublefree operation. The invention utilizes ball bearings for reduced friction and quiet operation. Bevel and spur gears are used to provide speed reduction between the outer driving surface and the inner driving member which causes the oscillating or vibrating movement of the roller.

With the foregoing in mind, it is an object of this invention to provide a new and improved vibrating roller.

A further object of this invention is to provide a new and improved mechanism for use with a vibrating ink roller for converting rotary motion of the roller into rotary and reciprocating motion.

A still further object of this invention is to provide a new and improved vibrating roller which is easily manufractured, quiet in operation and versatile in its use.

Additional objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice of the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein, and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings:

FIGURE 1 is a schematic view showing the general arrangement and orientation of a vibrating roller in accordance with this invention.

FIGURE 2 is a longitudinal sectional view taken along line 2-2 of FIGURE 1.

FIGURE 3 is a longitudinal sectional view taken along line 3-3 of FIGURE 1.

FIGURE 4 is a broken away view taken along line 44 of FIGURE 2.

FIGURE 5 is a sectional view taken along line 5-5 of FIGURE 2.

The invention herein relates to a vibrating ink roller 2 which is constructed and arranged so that as the roller 2 is caused to rotate it will be reciprocated back and forth along its longitudinal axis. The vibrating roller 2 is in peripheral contact with rotating roller 4 which is rotated by means not shown.

In accordance with this invention means are provided for converting the rotary motion of the ink roller into rotating and oscillating motion.

As embodied, the vibrating roller 2 is mounted on two stationary spaced apart spindles 6 which are fixedly attached to the frame 8 as best shown in FIGURES 1-3.

Mounted on the spindles 6, by means to be subsequently described, is an outer sleeve 10 which engages the roller 4. The outer sleeve 10 is mounted securly to inner sleeve 12 by screw 49 extending through connecting member 48 which is mounted on bearing 17A. Thus the bearing 17 and 17A comprise bearing means on which the outer and inner sleeve are mounted on the stationary spindles 6. While as shown in the drawing the outer sleeve is a single unitary member other accessory sleeves consisting of a split sleeve having two or more sections, for instance, can be press fit over the outer sleeve 10. It will be noted that in view of the manner in which the outer sleeve 16 is connected to the inner sleeve that the outer sleeve presents a smooth outer surface in that no screws, bolts or other external attachment means is required.

Fixedly attached to the inner sleeve member 12 by connecting means 14 is a substantially cup shaped first tubular member 15 having a key element 16 extending inwardly therefrom (see FIG. 4). The cup shaped member is provided with a bearing 17 to permit relative rotation between the cup shaped member and the spindles 6.

Fixedly connected to and extending between the spindles is a stationary body 18 on which are mounted converting means for changing the rotary motion of the outer sleeve to rotary and reciprocating motion.

Mounted on one end of the stationary body 18, by means of ball bearings 20, is a second tubular member 22 having a bevel gear 24 attached to one end by any convenient means such as screws 25. At the other end of the tubular member 22 is a key engaging means 26. The key engaging means consists of a bearing 28 mounted on shaft 29 within a groove in key element 16. The secnd tubular member 22 is mounted on the stationary body 18 by the ball bearings 20 so that it can rotate but not reciprocate.

Mounted intermediate the ends of the stationary body 18 is a shaft 27 mounted for rotation on bearings 31. At one end of the shaft 27 is a bevel gear 30 adapted to mesh with and be driven by the bevel gear 24. Intermediate the ends of shaft 27 is a spur gear 33. Mounted in the stationary body 18 substantially parallel to the shaft 27 is second shaft 32 having a spur gear 41 which meshes with and is driven by the spur gear 33.

Mounted in stationary body 18 is a third shaft 36 mounted on bearings 35. Intermediate the ends of shaft 36 is a spur gear 37 which meshes with and is driven by the spur gear 41.

At the other end of the stationary body 18 is third tubular member 40 mounted on bearings 43. The third tubular member 40 rotates about the stationary body 18 but does not reciprocate.

At the end (FIG. 2) of the tubular body 40 is a bevel gear 44, attached by screw means 42, driven by the bevel gear 39 mounted on shaft 36.

Attached to the second tubular body 40 are a pair of cam followers 46. The cam followers consist of a pair of spaced apart shafts having bearing means 48 mounted thereon.

Attached to the inner surface of the inner sleeve 12 is a cam 47 extending inwardly and between the bearings 48. (See (FIGURE 4.) The cam 47 and cam followers 46 as is apparent comprise converting means for changing rotary motion of the sleeve members to rotary and reciprocating motion.

OPERATION In operation, the outer sleeve is caused to rotate by the driven roller 4. The rotational movement of the outer sleeve 10 is transmitted by key 16 on the first tubular member to the second tubular member 22 to cause rotation of the bevel gear 24 and hence to actuate gears 30, 33, 41, 37, 39 and 44. Rotation of the bevel gear 44 causes rotation of the third tubular member 40 so that the cam followers 46 engaging the cam 47, and thereby cause the outer and inner sleeve to reciprocate back and forth along the axis of the spindles 6 thus converting rotary motion to rotary and reciprocating motion. The gear means are selected so that there is a speed reduction effected.

It is to be understood that the invention in its broader aspects is not limited to the specific elements shown and described, but also includes within the scope of the accompanying claims, any departures made from such elements which do not sacrifice its chief advantages.
